Title: Coolant monitor for welding or cutting appts. - where coolant pressure in flexible pipe forces a peg against a switch
Inventor: PSCHIERER JUERGEN
IPC: B23K9/28
Filed: 1975-07-30
Abstract: An arrangement for monitoring coolant flow through a flexible pipe, esp. on welding and cutting appts., is described, in which alteration in coolant pressure, and esp. a cessation of flow, provides a switch-off signal for uncooled, heat-sensitive appts. The novelty is that a pressure pin is pushed against the flexible pipe, the other end of the pin operating a switch. The pressure pin pref. forms part of a spring-loaded plunger located in a housing so that the spring pressure can be adjusted and the coolant pressure, if present, forces the plunger to push the switch to the "on" position.

Title: Electric train braking resistance temp. monitoring - using relays controlled by circuit producing quotient of voltage over current
Inventor: KLOTZ HUGO DIPL ING
IPC: G01K7/18
Filed: 1975-09-12
Abstract: An arrangement for temp. measurement in electrical braking resistances, in partic. as used in electrical rail systems, uses the variation of the impedance with temp. for determination of average temp. over the whole resistance. The arrangement permits a simple, easily maintained and economical construction. The voltage and current values across and flowing in the braking resistance (1) are sensed by a voltage divider (2) and series shunt (4) respectively, and input to an operational amplifier (6) via d.c. converters (3, 5). The amplifier forms the quotient of voltage divided by current and outputs a temp. dependent voltage to one or more trigger stages (8, 9) with defined threshold levels. The trigger stages operate relays (10, 11) used for indication and control of the temp. to avoid damage due to excess temp.

Title: Internal combustion engine with spark ignition - has turbulence chamber under exhaust valve in cylinder head and containing spark plug
Inventor: MAY MICHAEL G DIPL ING
IPC: F02B75/02
Filed: 1975-09-26
Abstract: The turbulence chamber (21) is formed inside the cylinder head below the exhaust valve seat (17) and has an oval cross section. A channel like depression (26) leads from the inlet valve seat (14) to the turbulence chamber and its height steadily increases as it joins the chamber. The piston crown (9) is flat and forms, with the depression (26), a channel at top dead centre leading to the turbulence chamber. A single spark plug is provided and located in the turbulence chamber. The advantage claimed is that the channel from the inlet valve to the turbulence chamber not only improved the combustion gas turbulence but also assists the scavenging action on the exhaust stroke. The engine operates on low octane rated fuel with a very lean fuel mixture to favour exhaust emission.

Title: General anaesthetic appts. with carbon dioxide control - has indicators and alarms triggered by deviations in exhalation rate
Inventor: MOYAT PETER DR PHIL
IPC: A61M16/10
Filed: 1975-09-27
Abstract: The monitor and control system for general anaesthetic apparatus operates by using the measured exhaled CO2 concentration, according to a nominal value, to govern CO2 supply for inhalation. Deviations from the nominal value in either direction are indicated as well as anomalies in the expiratory CO2 concentration-time ratio. A shunt leading to the CO2 absorbers is opened or closed or in the case of semi-open or open types of anaesthetic apparatus CO2 is supplied from a pressurised gas bottle. Inspiratory CO2 supply may be indicated optically or acoustically. If the CO2 concentration in the expiratory branch of the apparatus remains constant (breathing stopped), the sensor triggers an alarm signal, as long as the system is set to spontaneous breathing.
